Title: Conveyor system with rollers driven only under load - has roller group driven by toothed belt through toothed wheels and second toothed belt for drive from motor
Inventor: WEGENER WOLFGANG DIPL ING
IPC: B65G47/26
Filed: 1991-04-09
Abstract: System comprises a series of driven rollers at right angles to the direction of travel of the conveyed goods. Rollers are mounted in fixed bearings and rotational speed can be braked as desired. Power is from a common drive through friction couplings. Drive is transmitted by several toothed belts instead of a single endless toothed belt claimed in a previous main patent. One toothed belt passes over and drives the toothed wheels of a number of rollers. Each toothed wheel is connected to the adjacent roller via a friction drive. Drive from the motor to one of the toothed wheels is by a 2nd. toothed belt. A conveyor length (1) has parallel rollers (2) conveying goods from a loading point (4) to a processing station (50). Rollers (2) have friction drives ensuring that the drive system (5) and roller tube (2) are only connected when the roller (2) is under load. Series of rollers (2) is driven through a continuous toothed belt (61) passing around the toothed drive wheels (81) of the whole series of rollers (2). Belt (61) runs around approx. one half of the circumference of each end roller, but only makes tangential contact with the top and bottom of the intermediate rollers (2). Toothed wheel on the shaft of a drive motor (5) is connected via a 2nd. toothed belt (62) to a 2nd. toothed wheel (81) on the driven roller (2) at the end of the series of rollers.2). USE/ADVANTAGE - Conveyor system prevents transported goods from closing up to contact each other with damage potential and gives longer belt life.

Inventor: BUTZEN EDGAR
IPC: D05B65/00
Filed: 1991-06-01
Abstract: In a process and device for shortening the needle thread end at the start of sewing in double-lockstitch sewing machines, the catch-thread device (23) of a thread cutting device (22; 60; 90) existing on every machine is moved into its thread catching position during the first stitch-forming cycle, whereby, either the catch-thread device (23) movement at a suitable time or a stream of compressed air from a compressed air line (81) ensures that at least the leg of the needle thread loop on the spool side is engaged by the catch-thread device (23). When the catch-thread device (23) moves back into its initial position a part of the needle thread end is cut off. In addition, the needle thread is either clamped beneath a leaf spring (44) or pushed under the sewing foot through an adequately great feed distance and thus held by friction.

Patent DE-4204805-A1 (DE)
Inventor: KOTSCHY BERNHARD
IPC: B04B11/04
Filed: 1992-02-18
Abstract: A solid matter collecting separator (1), in particular a three-phase centrifugal separator, is used to separate solid substances from liquids, in particular to regenerate used emulsions, preferably cooling lubricants, but also detergent solutions. A solid matter-laden liquid continuously flows into the separating chamber (4) of the separator (1). One or several liquid phases purified from solid substances flow out continuously as well. The separator (1) is designed for manual removal of the solid phase, also known as sludge. From time to time the volume of the liquid inside the separating chamber (4) is measured and compared to a minimum volume previously determined for each type of separator. When the measured volume falls below said minimum volume, the separator (1) is cleaned by removing the solid substance (5) (sludge) accumulated in the separating chamber (4). Operation of the separator (1) needs to be interrupted only for a short time in order to detect the amount (5) of solid substances deposited in the separator (1). The capacity of the volume provided to receive sludge is better used. The cleaning cycles are longer.
